A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

Lessons Learnt From Long‐Term Monitoring of River Restoration in an English Chalk Stream

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT River restoration can be difficult to evaluate due to insufficient monitoring over timescales too short to adequately capture physical and ecological response. To better understand restoration outcomes, this study quantified changes in physical habitat (depth, velocity, substrate composition) and macroinvertebrates at two restoration projects ...

From snapshots to continuous estimates: Augmenting citizen science with computer vision for fish monitoring

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study presents an end‐to‐end computer‐vision pipeline for monitoring fish migration using underwater video. We integrate field camera deployment, annotation, model training and automated in‐season counting to generate continuous, high‐resolution data on river herring spawning migration.

Centering Care in Transformative Climate Change Education: A Theoretical Framework for Communal Learning Ecosystems

open access: yesScience Education, EarlyView.
ABSTRACT Research‐practice partnerships addressing climate change education face challenges navigating political resistance, epistemic tensions, and systemic inequities within schools and communities. Recent scholarship has outlined transformative climate change education (TCCE) as requiring the simultaneous transformation of curricula, pedagogies, and

Veterinary students’ choices of clinical extramural placements are associated with their final‐year examination performance

open access: yesVeterinary Record, EarlyView.
Abstract Background UK veterinary students must complete 20 weeks of clinical extramural studies (EMS) in placements of their choice. We investigated the associations between EMS choices and performance in the final‐year ‘livestock and One Health’, ‘equine’ and ‘small animal’ written examinations.
